Do I also have adobe shockwave player???

I have noticed a few odd things that make me wonder if I have the adobe shockwave player

I don't recall ever installing that and it concerns me because I have never updated it if I have it ( and thus might be vulnerable)

Here is why I wonder

I notice in the add ons that have been used by internet explorer, I have this ite:

Shockwave Active X    SwDir.dll

it says it is located in

C:\Windows\System32\Adobe\Director

But I do not find that even when I click show hidden files and folders in the folder options

Also in

C:|Windows\Downloaded Program Files

There is this item

Shockwave Active X control   4kb size  version 11.5.1.601

So I'm really confused. I do not see anything about Shockwave Player in

 C:\Program Files 

Start>Programs

or in

Control Panel>Programs>Programs and Features ( I have Vista) 

I don't think I need this program but not sure how to delete it as it doesn't seem to show in the usual places

Could it be just some left over junk from a previous time?
